    Question Rationalizing an equation?

    Hey, I already asked this question, but, as I was just learning how to use the site, I posted it in the wrong area, so it probably won't get an answer, so please forgive the repost. I was wondering, is there an equation that rationalizes 1/(a'th root of x+b'th root of y)? If so, what is it'?

    Thanks,


    Robbie

    So your function is \frac{1}{\sqrt[a]{x}+ \sqrt[b]{x}}? With a and b different, there isn't going to be any good way to do that.

    Are you sure? Because if that is so, my friend and I are planning on publishing an equation we came up with to do just that. I won't post the equation here yet because someone could steal it, but thanks for the help!

    Someone might "steal" it? What in the world would they do with it? You can't make money on things like that. But if you think it is important that you be given credit for it, then publishing here or somewhere else on the internet where you can get a ''time stamp", is enough to prove priority.

    Actually, my goal is to get this published in some type of math journal, which could be worth a lot when I'm trying to get into colleges two years from now. I would consider that a good enough reason to not post it here.

    Okay, but I am puzzled why you think the colleges would prefer to think you did it when you are two years older than whatever age you are now. I think I would be more impressed by something done by a person who was 17 rather than when he was 19.

    No, I'm publishing it as soon as possible, I'm just publishing it in a more reputable way than through a time stamp on a math forum.
